LRAD Rolls Out Long-Range Mobile PA System

LRAD has debuted a new mobile PA system that boasts the ability to blast intelligible audio over an area of 2 square miles.

The new Mobile Mass Notification System, which LRAD described as a "long range acoustic hailing device," consists of a ruggedized trailer sporting a folding and telescoping mast that can lift the system's speakers to a height of 30 feet. The acoustic array can broadcast in a 360-degree ring with a radius of about 0.8 miles when configured with the four-emitter LRAD-360-4. That provides a coverage area of 2.01 square miles.

Other features include:

XLR and RCA input;

RCA output for daisychaining additional amplifiers;

8-pin speaker out;

Remote and hard power on/off switches;

Remote and hard volume control.

Pricing has not been publicly announced. Further information can be found on LRAD's site.
